When the contact separation type friction power generation device is vibrated by external force, the second substrate 6 vibrates up and down, so that the second dielectric material layer 5 on the second substrate 6 is in contact separation with the first dielectric material layer 4 on the first substrate 3, and due to the fact that the electron affinity of the first dielectric material layer 4 is different from that of the second dielectric material layer 5, the surfaces of the two dielectric materials generate equal and opposite charges, a potential difference is formed, and output current is generated and output through the metal electrode.
